Structure and Functions of Areolar Tissue
Areolar Tissue is a common form of loose connective tissue.
1.0 Where in the body is Areolar tissue ?
Areolar tissue is found in many locations around the body.
One important area is the skin (areolar tissue is
found in both the dermis and sub-cutaneous layers
of the skin - see diagram).
The areolar tissue located in the skin binds the outer
layers of the skin to the muscles
Areolar tissue is also found in or around mucous
membranes, and around blood
and the organs of the body.
2.0 The Structure of Areolar tissue
Areolar Tissue is loose connective tissue that consists of a meshwork of collagen, elastic tissue, and reticular fibres - with many connective tissue cells in between the meshwork of fibres.
The fibres that form the mesh structure of areolar
- Collagen Fibres
- Elastic Fibres
- Reticular Fibres
The different types of cells embedded within the areolar tissue include:
- Plasma Cells
- Mast Cells, and
All of the above (fibres and cells) are embedded
in a semi-fluide ground substance - which
is similar to the ground substance in which
the chondrocytes arelocated in hyaline cartilage

3.0 The Functions of Areolar tissue
Areolar tissue binds skin
to the muscles
This loose connective tissue also forms a link between organs
- while also enabling a high degree of
movement between adjacent body parts.
The key functions of areolar tissue can be summarised as providing:
- Strength, and
